Long-Term Portfolio Simulation - For XVA, Limits, Liquidity and Regulatory Capital

Long-Term Portfolio Simulation book

In today’s regulatory environment, it is becoming increasingly important to answer the question of why a particular model or calibration method is being used by something better than “we have always done it this way” or “this is consistent with market practice”. Even when the model is indeed part of market practice it has to be justified on its merits and its limitations must be clearly understood.

 

Published in September 2014, “Long-Term Portfolio Simulation - For XVA, Limits, Liquidity and Regulatory Capital” provides a comprehensive step-by-step guide to every aspect of constructing and using a long-term portfolio simulation models. A comprehensive description of advanced techniques for model construction and calibration includes application examples to different asset classes.
